President Barack Obama had some burns for Donald Trump during an
appearance on "Jimmy Kimmel Live" Monday night.

“Do you ever actually laugh when you watch Donald Trump?,” Kimmel
asked Obama, who responded that he does, most of the time.

"I don't tweet at 3 a.m. about people who insult me," Obama
added.

In one segment, Obama read some mean tweets about himself.

"Barack Obama, bro, do you even lift?," read one tweet. "Well, I
lifted the ban on Cuban cigars — that's worth something," he
said.

One tweet was from
Trump himself: "President Obama will go down as perhaps the
worst president in the history of the United States!"

"At least I'll go down as a president," Obama quipped.

He jabbed Trump again later when talking about actor Bill
Murray's
recent visit to the White House. After Murray beat Obama in a
game of putting golf balls into a glass, Obama said "He won
repeatedly ... The glass was rigged!"

Obama was traveling on the West Coast Monday to attend
fundraisers supporting Hillary Clinton's presidential campaign.
His motorcade was
spotted leaving film executive Jeffrey Katzenberg's home
Monday night.

He has also been making the rounds in battleground states on
behalf of Clinton and a number of down-ballot Democrats.

On the campaign trail, Obama has taken a considerably more
foreboding tone toward Trump, joining other Democratic all-stars
like
Sen. Elizabeth Warren of Massachusetts,
Michelle Obama,
Joe Biden, and others calling Trump unfit for the White
House.
